T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is a PDF document flagged by ML classifiers and ClamAV as malicious. It contains an embedded URI pointing to a suspicious domain, 'kuzutuzo.ru', which is likely part of a phishing or malware distribution scheme. The document body appears to be obfuscated or corrupted, but the presence of external URLs and the overall detection strongly suggest a malicious intent, potentially leading to further compromise.

External URI info PDF_URIPDF contains an external URL action
-
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL https://kuzutuzo.ru/award?keyword=adolescent+friendly+health+services+pdf
